General one-loop formulas for decay $h\to Z\gamma$

Abstract

Radiative corrections to the $h\to Z\gamma$ are evaluated in the one-loop approximation. The unitary gauge gauge is used. The analytic result is expressed in terms of the Passarino-Veltman functions. The calculations are applicable for the Standard Model as well for a wide class of its gauge extensions. In particular, the decay width of a charged Higgs boson $H^{\pm }\to W^{\pm }\gamma$ can be derived. The consistence of our formulas and several specific earlier results is shown.
